I'm calculating for a soccer field. The GR has to be below 50. To be sure I meet the requirements, I now put over the soccer field GR observers in a grid of 10 by 10 meters. When done so I have to check the output and check every line for the result.
Is there an other way to do this? For instance a measurement layer which gives the results just like the average with ISO lines but than with the ISO lines for the GR values?
